Description
Biotage ELSD-A120 Evaporative Light Scattering Detector Overview
The ELSD-A120 detects compounds by nebulizing the column effluent, evaporating the mobile phase, and measuring light scattered by the remaining analyte particles. This makes it effective for detecting non-volatile compounds that lack UV chromophores — including sugars, lipids, surfactants, and other non-UV-active analytes that conventional UV detectors miss.
It uses a 480nm Class 1 LED light source paired with PMT detection and digital signal processing for stable, low-noise output. The nebulizer and evaporator temperatures are independently adjustable, and gas flow is controlled with automatic shut-off for safer, more consistent operation across different solvent systems.
Biotage ELSD-A120 Evaporative Light Scattering Detector is commonly paired with Biotage flash chromatography systems for compound purification and detection, but also integrates into standard HPLC workflows for pharmaceutical, natural products, and general lab analysis where non-UV detection is required.
This Biotage ELSD-A120 is offered fully refurbished and tested, in working condition by Alliant Scientific.
